Let's divide 398409 by 98
We want to figure out the number of times 398409 can be divided by 98.

On to step 1:
If we divide 3 by 98, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 98

Let's proceed to step 2:
98 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 98

Advancing to step 3:
398 divided by 98 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 392 from 398 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 98

Let's proceed to step 4:
When dividing 64 by 98, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 98

Moving on to step 5:
98 goes into 640 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 406.0
If we subtract 588 from 640, we get 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 98

Advancing to step 6:
When dividing 529 by 98, we get 5 with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 4065.0
Subtracting 490 from 529 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
If we divide 390 by 98, we get 3 and a remainder of 96.
The number 3 becomes the next digit in our result. 
Result so far: 4065.3
If we subtract 294 from 390, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 8:
When dividing 960 by 98, we get 9 with a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 4065.39
The remainder is 78 after subtracting 882 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
98 goes into 780 7 times with a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 4065.397
Deduct 686 from 780 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 10:
98 can be fit into 940 9 times, resulting in a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 4065.3979
If we take 882 away from 940, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 11:
98 can be fit into 580 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 4065.39795
If we subtract 490 from 580, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
98 can be fit into 900 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 4065.397959
The remainder is 18 after subtracting 882 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
98 can be fit into 180 1 times, resulting in a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 4065.3979591
Subtract 98 from 180 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 14:
When dividing 820 by 98, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 4065.39795918
If we subtract 784 from 820, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 4065.39795918 with a remaining 3.6e-08.
